To prepare for the impending launch of StarCraft II: Heart of the Swarm, we’re now expanding the ongoing beta test to include additional players. Any players who pre-purchased the expansion digitally on Battle.net on or before December 18 are now flagged for beta access. Additionally, players who digitally pre-order after December 18 will be added to the beta in waves on an approximately weekly basis. The beta client can be downloaded here. Please keep in mind that although anyone can download this client, only players who have obtained beta access will be able to log in.
Select retailers such as Amazon are also offering promotional beta key codes for players who pre-order Heart of the Swarm at retail. Be sure to check terms and availability with the retailer. More details on the Heart of the Swarm launch activities will be announced in the coming weeks and months. Until then, we hope to see you in the beta test and hear your feedback!
Update - December 21, 2012 - 5:00 p.m. PST: All players who pre-purchased the expansion digitally on Battle.net on December 19 & 20 are now also flagged for beta access.
